摘要
微卫星又称简单重复序列,是一类由几个核苷酸(一般1-6个)为重复单元而形成的串联重复序列.由于它具有含量丰富、多态性高、共显性和检测方法简单等优点,而广泛应用于品种鉴定、种质资源保护、遗传作图、基因定位和QTL分析等方面.文章就微卫星标记在水稻中的开发和应用进展作一概述.
Microsatellite, also known as simple sequence repeats, is tandom repetitive sequences composed of motif of 1-6bp. Due to its abundance, high level of allelic diversity, coodominance, simple process, it has been widely used in variety identification, germplasm classification and reservation, genetic mapping, gene tagging, and studies of QTLs. The progress of new development and application of rice microsatellite was dicussed in this study
